question for web programmers

This is a technical question.
I have a friend that has paid for an online course. he logs in and then there are some videos that he watches. He says in his agreement with the course provider, it said he cannot copy or save the videos on his computer. if they catch him doing such thing, they will end his account.
I know about several video downloaders for firefox, like downloadhelper and flash downloader (i believe we will need some kind of flash downloader because the video seems to be in flash)
now my question is: if we download the videos this way, is it possible for the site owner to find out? if yes, how?

1. i dont think so.
2. you can get what ever u want in youtube or in google.
3. try torrent site to get ebooks.
4. try stackoverflow.com or that particular programming related forums to get more examples and tutorials.

paying for course if rubbish. if u have strong will, u can learn even from bit of paper.. see bill gates how he built a OS out of crap :d
